Whatever you have bound to the WORepetition 'item' will be set when
the action method is called. Let's say you're iterating through
departments, and have a variable "currentDepartment" bound to the
WORepetition's item. If you have a WOHyperlink anywhere inside the
WORepetition, when the action method is invoked, you can check the
"currentDepartment" variable to see which iteration of the
WORepetition the user clicked on. You follow? I think that gives you
want you need to do what you want.
You might want to consider storing the already instantiated pages in
the particular WOComponent, rather than in WOSession, but either one
could work and could be appropriate, depending on what's going on.

Hi All,
is it possible to pass parameters to action methods or to get the
attributes from the element that called the action method?
my problem:
I want to build a menu with hyperlinks. Idea: a WORepitition with a
Vector for the menu entries with names and pages that shall be
called. Works fine. Problem: when a reload is performed, clicking a
menu entry causes the corresponding page to be instantiated again,
because apparently the hyperlink using the pageName attribute calls
a pageWithName() that always create a new page.
A solution could be working with an action method that stores all
already instantiated pages in the session. For I am using a
WORepitition containing one WOHyperlink I only can declare one such
action method. But this action method must return different pages
depending on the clicked hyperlink, so I have to pass a parameter.
Does anybody have an idea how to do this?
TIA
